ISToTONOMUS SATRAPA, Castelnau. 



Elongate-oval, subparallel, strongly convex. Black, legs piceous- 

 red. Head large (5 mm. across eyes), convex; eyes convex, deeply 

 enclosed in swollen orbits on posterior and lower sides. Prothorax 

 cordate (5-2 x 6-3 mm.), wider across apex (5 mm.) than base 

 (4-3 mm.), lightly rounded on sides; basal angles obtuse; basal 

 impressions wide; posterior marginal puncture distant from basal 

 angle (0-6 mm.) on inner side of marginal channel. Elytra oval 

 (13-2 x7'6 mm.), convex, subdepressed near suture, strongly 

 declivous to sides and apex; humeral angles not marked; basal 

 border joining lateral border without interruption at humeral 

 angles; striae strongly impressed; interstices lightly and evenly 

 convex, third 5-punctate, fifth impunctate, seventh 4-punctate. 

 Intercoxal declivity of presternum narrow and rounded in middle; 

 of mesosternum wide, concave. Tarsi with fifth joint spinulose 

 beneath, two or three strong short spinules on each side. Length 

 24-5, breadth 7*6 mm. 



Hah. — Vic. : Crooked River (two specimens [5] in Howitt 

 Coll.). 



When in Melbourne recently I found in the Howitt Collection 

 two specimens ticketed ^'•Feronia sa^ra/)«,Casteln., Crooked River." 

 A specimen (9) has been in my possession for many years, without 

 locality, but I passed it over when reviewing the genus Nolonomus 

 last year because Castelnau's description of the elytra as "rather 

 depressed" seemed imsuited to this unusually convex species. 

 Compared with N. 'pluripnnctatns, SI. {=N. satrapa, SI., not 

 Castelnau), the following differences are noted (unfortunately I 

 am only able to compare the ^ of N. satrapa with the $ of N. 

 pluripimctatus) : — Form more convex and parallel; prothorax less 

 narrowed to base, posterior marginal puncture further from basal 

 angle; elytra with fifth interstice impunctate; tarsi with onychium 

 spinulose beneath. From N. gippsie)isis, Casteln. (of which 

 Chaud. suggested it was merely a variety), N. satntpa is distinct 

 by its narrower and more convex form; larger head; narrower 

 and less depressed prothorax with posterior marginal puncture
